How to Plant and Raise Sweet Corn

Find a medium to large plot of land on which to plant the corn. The soil should be well-drained and the plot in a sunny location. For the best results, find an area with enough space to plant corn in short rows instead of one long row. This will increase pollination.

Start working the soil with a spade two weeks after the last frost date. Sweet corn cannot tolerate frost and will not grow well in soil temperatures under 55 degrees F. Work the soil 6 to 10 inches into the ground, removing rocks and trash and breaking up any soil clumps. Incorporate organic compost or manure into the soil at this time as well.

Plant the corn seeds 1-inch deep and 9 to 12 inches from one another, in rows about 30 to 36 inches apart. Tamp down the soil over the seeds and water deeply. Keep the soil moist while the seeds grow and take root.

Control the weeds around the corn with a small cultivator. Weeds compete with the corn for nutrients and water. Be careful not to tear the roots, as they are shallow.

Fertilize the plants when they are about 2 feet tall. Use a balanced, complete fertilizer and follow the directions on the package for application instructions.

Harvest the morning or evening when the silk has turned dark brown. The kernels should be juicy and fully grown on the tip. Twist the ear quickly to remove it from the stalk. Use the corn soon after it is harvested.
